Abstract: To conduct comprehensive treatment effectiveness studies, evaluators must frequently track, locate and interview service recipients long after program participation has ended. For some populations, this is an arduous task. But, despite wide variations in retention rates, the published literature from follow-up studies rarely provides information on their tracking, locating, or interviewing techniques. The present report concerns a 12-month follow-up study of individuals who were homeless and mentally ill, which achieved a remarkably high retention rate—over 70%. Quantitative information is presented on client characteristics related to locatability and agreement to be interviewed, as well as qualitative information on successful techniques, from a focus group session with research interviewers.
